isaae BATH-FIXTURE VALVE.

Application filed January 18, 1924. Serial No. 687,1e1.

To all'whom it may concern:

Be it known that I, ARTHUR a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain newand useful Bath-Fixture Valve.

This invention pertains more particularly to a new and useful interchangeable working unit particularly adapted for bath fiX- tures and shower valves. As is well known in the art, the working units of valves of this character in use are subjected to tremendous torque and other strains both when turning the stem down too tightly or releasing when ithas become tightly set, due to'expansion or other causes. Not infrequently under such conditions, parts of the old cast structures generally used prior to my invention were broken and the valve rendered useless. Another disadvantage of the cast working units in use prior to my invention, was the difiiculty in properly alining one part with respect to another owing to the fact that it was impossible in -actual practice, to maintain uniformity in the manufacture or casting of these parts. Moreover, theywere,

very brittle and incapable'of giving slightly under great strain without breaking particularly the stem, did. not machine-well, and did not possess sufiicient tensile strength to properly withstand the tremendous strains and stresses imposed thereon. Further, the threads cut in the cast bonnet on WlllOll the stem turned were easilybroken and'lasted materially toi thelongevity of the device.

It is aiurthr object to provide aunit of this type which can be readily and quickly adjusted to'aiccfommodate walls or partitions of varying thickness. It is a further object to provide a resilient stem which will give slightly under abnormal strains.

The above and other features of novelty,

advantages and capabilitieswill become ap W. Gon'rz,

parent from a detailed description of the accompanying drawings, in which I have illustrated 'one form of my invention, but the construction there shown is to be understood as illustrative only, and not as defining the limits of my invention.

In the drawings:

Fig. 1 is a view partly in section, of a valvefbody with the working unit in elevation, illustrating one form of my invention.

Fig.- 2 is a sectional View of the same showing a portion of the valve stem in elevation. Fig. 3 isa sectional view of a portion of the valve body showing my interchangeable working unit removed and the valve body closed with a screw-threaded plug, and,

Fig. 4 is a diagrammatic view illustrating a piece of solid brass rod and showing in dotted lines the form taken after being machined to produce the bonnet ofmy working unit.

Referring to-the drawings in detail, 10 indicates the valve body which, in practice or partition. the head of which is connected with suitable screw-fitted pipes 11 and 12 leading to and from a source of hot and cold water. The neck portion 13 which extends through the wall or partition, in practice, is, near its outer or free end, interiorly pro- .vided with irorrpipe threads 14. The

working unit comprises a valve stem 15, swivel disc 28, bonnet 16, adjusting and stufiing gland, 17, and an adieistable escutcheon holder 18, all of which parts are cut from solid brass rods of the proper diameter or size and then machined to the forms shown. The bonnet whose outer end terminates in a hexagonal flanged head, 20, adapted to tightly engage the outer end of the valve body when properly screwed down, is

provided with 7 pipe threads, designed to register with .the threads on the interior of the valve body. Extending through the bonnet is the solid brass rod valve stem 15 which, near its inner end, is. provided with acme threads, 21, which turn in similar threads 22,'formed on the interior of the bonnet. The -bonnet,j16' is provided on the interior, intermediate its ends, with an integral inwardlyex'tending flange23, and adjacent this flange and surrounding the stem is a suitable packing 24. The bonnet at-its outer end is interiorly provided with pipe and when installed extends through a wall the entire length with pipe threads.

Either end of this nut is designed to screw into the outer end of the bonnet, 16, as desired, and into engagement with the packing 24 to compress the same for forming a water tight fit around the stem 15; The cup shaped escutcheon holder 18, is interiorly threaded throughout its length with pipe threads and is adapted toteles'copically screw on to either extension of the glaiid 17 for holding the escutcheon properly in place and protect the threads on the gland. Asit is desirable in practice, that the inner edge of the escutcheon holder be screwed up against the gland 17, as shown in Fig. 2,

the bonnet and 'escutcheon' holder.

I can readily and quickly adjusted-tosuit the varying conditions in use. The outer end of the resilient valve stem is provided with two transverse screw-threaded openings 26 at right-angles, to receive the usual china I index handle;

ByI providing the valve body with pipe threads, it enables the plumber to .insert an ordinary black iron plug 27 in the valve body opening, thus leaving the' stem and china intact'in abox in'the store roomuntil such time as they are ready to turn over the job complete for architectural approval. ,With the ordinary valve hereto fore on the market, this was not possible and frequently, where the working unit of the valve was put in place before-thev job was completely finished,'they were damaged or .jjbr'oken by careless workmen standing on "the stem, or from other causes.

ient valve stem is cup shaped at its inner end and has rotatably mounted therein a disk- .28 towhich is secured by means of a screw 29, a suitable washer 30, adapted to cooperate with the outlet or port of the valve body when the stem is operated in the usual way. The disk 28 is held in the stem by bending the inner end of the stem inwardly around the neck 28 of the disk.

In manufacturing the'working unit, that is the valve stem, escutcheon holder, adjusting' and stufiing gland bonnet and disk, I take solid brass rods of proper dimension,

which rods are cut into'pieces of the proper length, then turned .down to approximate the form of-the finished article, and the threads herein describedare then cut on the parts thus formed. The exposed portions are then polished and plated. Due to the fact that they are constructed of solid brass they can be polished. and plated muchrods, easier'than the old cast parts.

From the description thus far it will vantages.
